Eduardo Camavinga has reportedly informed Rennes supporters that he intends to leave the club, amid interest from Manchester United.
The 18-year-old midfielder has entered the final year of his contract and has turned down numerous offers to stay with the Ligue 1 outfit.
Rennes are now at risk of losing their highly-rated teenager for free and are therefore prepared to sell him this summer for a fee in the region of £25m.
According to the Daily Mirror, United are monitoring Camavinga's situation and have made an approach to the Frenchman's agent, Jonathan Barnett.
Ole Gunnar Solskjaer is keen to bolster his squad with a defensive midfielder as the Red Devils boss is currently forced to rotate Scott McTominay, Fred and Nemanja Matic in this position.
United have already spent over £110m on summer signings, with the arrivals of Jadon Sancho from Borussia Dortmund and Raphael Varane from Real Madrid.
Camavinga made 39 appearances across all competitions for Rennes last season and so far this campaign he has featured in all four of their competitive fixtures, though only one of those has been a start.
